Carbofuran-containing plant protecting compositions

Abstract

The invention relates to carbofurane-containing plant protecting compositions. More particularly, the invention concerns insecticide compositions with improved plant growth accelerating properties, containing 1 to 50% by weight of 2,3-dihydro-2,3-dimethyl-7-benzofuranol methylcarbamate optionally along with usual amounts of additives conventionally used in the manufacture of plant protecting compositions, which comprises 50 to 99% by weight of a carrier granulate prepared by partial hydrolysis of vegetable waste matters, preferably corn-cob, corn-stalk, chopped wood or sawdust derived from broad leaved trees, rice hull, read or broaken reed, known per se.

We claim: 
     
       1. An insecticidal composition with improved plant growth accelerating properties containing 1 to 50% by weight of 2,3-dihydro-2,2-dimethyl-7-benzofuranol methyl carbamate and 50 to 99% by weight of a carrier prepared by partial hydrolysis of granulated vegetable waste matter selected from the group consisting of corncobs, cornstalks, chopped wood or sawdust from broad-leafed trees, rice hulls, and reeds. 
     
     
       2. The insecticidal composition defined in claim 1 which consists essentially of 5 to 10% by weight carbofuran and the balance partially hydrolyzed granules of corncob as a carrier. 
     
     
       3. The insecticidal composition defined in claim 1 wherein the carrier is prepared by hydrolysis of the granulated vegetable waste matter by steam. 
     
     
       4. The insecticidal composition defined in claim 1 wherein the carrier comprises granules of vegetable waste matter having a particle size from 0.02 to 2 mm. 
     
     
       5. The insecticidal composition defined in claim 1 which consists essentially of 10% by weight carbofuran and the balance partially hydrolyzed granules of corncob. 
     
     
       6. A method of promoting plant growth which comprises the step of applying to a plant growth site an effective amount of a composition containing 1 to 50% by weight of carbofuran uniformly distributed on a steam hydrolyzed granulated vegetable waste carrier selected from the group consisting of corncobs, cornstalks, chopped wood or sawdust from broad leaved trees, rice hulls and reeds, said granulated vegetable waste carrier constituting the balance of the composition.
